Use of Ultrasonic Analysis in the Testing of Isolating Valves
Offshore installations use a series of isolation valves to divert the flows from the various pumps. One of the main reasons a pump test can "fail", is if the isolating valves are passing. This article describes testing the isolating valves using ultrasonic analysis. Overhaul of an isolating valve costs significantly less than undertaking an unnecessary pump major overhaul,
